基于计算机仿真计算的铁路接触网钢梁分析与设计

Analysis and design of steel girder of railway catenary based on computer simulation and calculation

常规的接触网支架跨度在铁路多股道区框构顶进工程中已不能满足工程需要,需要设计超大跨度的钢梁。本文以计算机有限元仿真技术为基础,基于仿真计算结果,结合理论推导,实现了超常规铁路接触网钢梁的分析与设计。该方法能显著缩短设计周期,提高铁路接触网特殊钢梁的计算准确度,对今后遇到的类似接触网特殊钢梁设计有着重要的指导意义。

The ordinary span catenary couldn＇t satisfy the need of the project in framed jacking engineering of multi-track railway area, so it had to design an super-span steel girder of catenary. Based on the technology of simulation of computer finite element and applied the calculate result, it was implemented the analysis and design of super-span steel girder of catenary. This method could decrease the period of design and improve the degree of accuracy. It also had important significance to guide the design of special catenary steel girder in similar project.
